TV show aggregator

 Both ABC and FOX recently announced that they will be putting their shows online after they have been aired on TV.  I just had the idea that it would be useful if there was a TV show aggregator that would pull in different shows for a user from various sites.  So users would have the ability to tell the aggregator which shows they want to see and the aggregator would set off to pull in shows that the user has included in thier list.  People would be able to mix and match any shows or even other videos from the web.  In a way, this would give people the ability to create their own customized TV channels which they could further share with others or maybe they could stream them from their computers to their television sets.  This would be huge disruption to the current TV network model.  I think something like this could be a successful business idea.
